Since changing the SSID drops the network connection you can't push out a change to the machines.
Let's say no.
If you actually CHANGE it you will drop. Some commercial AP have the ability to add multiple SSID to the same vlan. You could then run in parallel for a while and tell your uses to use the new one and then remove the old. A couple of brands of AP actually have a feature that allows you to not allow new sessions to a SSID but leave it active.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
